Are you using the vanilla Thunderbird version from Mozilla or a version provided via your distributions repository?

linux crashids aren't useful unfortunately. Please post your Windows crash IDs

Here are some of my Windows 10 crash ID's Thanks, Ed

I'm using the Fedora 25 repository version. Note that I also have the same issue with Windows 10. Before version 52 I can't remember TB crashing going back to version 1.0.2

This crash, @ nsImapCacheStreamListener::OnStopRequest, we hope to have fixed in 52.1.1 which should be out in the next 1-2 weeks. if it doesn't solve it, then please update this topic

Well TB 52.1.0 64 bit from Fedora 25 repository seems to fix the issue. and TB 52.1.0 32 bit on Windows 10 does NOT fix the issue.

According to Wayne Mery (previous reply) TB 52.1.1 should fix the issue and be out in the near future.

So, I will mark it as solved for now and wait for the Windows 10 TB 52.1.1

Thanks to whoever fixed it, I have been using TB for many years and really did not want to change my EMAIL client.
